Application led March 29, 1917.

To all whom t may concern:

Be it known that 1, Orr-1o lli/1. Or'rn, a citizen of the United States, residincat the city hautauqua and State of New York, have invented certain new and useful improvements in Sheetlllletal Doors, of which the following, taken in connection with the accompanying drawings, is a specication.

The invention relates to sheet metal door construction; and the object of the improvement is to provide a paneled door with boxed or hollow frame so attached to the panel that no edge of the metal is exposed to View and a smooth neat nish may be attained; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

ln the drawings, Figure 1 is an elevation of a sheet metal door. Fig. 2 is a sectional view of the stile or cross rail of the hollow frame for a door which has the same appearance on both sides. Fig. 3 is a similar sectional view of a single sided door, the inner side being flattened and having a lengthwise bead which covers the edge of the sheet metal which forms one edge of the stile or cross rail, the bead on the other edge turninn that edge toward the panel and the edge of the puanel abutting against the tubular stile or cross rail and being welded thereto; and Fig. i is a sectional view of a portion of the panel stile or cross. rail with the panel inserted between the edges of the tubular stile or cross rail instead of on the outer side as in Fig. 3, and spot welded thereto7 one of the sides being straight thereby differing from the design shown in Fig. 2. Fig. 5 is a sectional perspective view showing a modification of the construction shown in Figs. 2, 3 and 4 in which the panel is shaped to form one side and the edge of the stile or cross rail and an angular plate is provided for the opposite side, whichplate lits closely between the beaded or turned edge of the first sheet and the inner corner of the outer edge of the plate being turned in a bead and spot welded to the larger plate after springing into engagement, the manner of inserting the plate being shown in dotted line. Fig. 6 is a fragmentary view., in perspective, of `the angular plate employed in Fig. 5.

' Like characters of reference refer to corresponding parts in the several views.

The nulneral 10 designates the panel por tion, the numeral 11 the stiles, and 12 the cross rails.

For the double paneled door shown in Fig. 2 or they single paneled door shown in Fig. a, the stiles 11 and cross rails 12 of the .door frame are shaped from single strips of metal folded angularly lengthwise of the central portion andA having the curved or otherwise molded inner edge 13 for the inner molded portion of the stile or cross rail, the plate being continued in a contacting portion lil with the panel plate 10 and a bead 15 inturned on the inner edgeof the plate to thereby turn the edge or edges of the folded strip forming the stile or cross rail toward the panel plate l0, giving a pleasing finish and at the same time holding the panel plate 10 firmly so that it can be spot welded at spaced intervals along the contacting portion 1t.

When it is desired to have a flat inner side to the door without the bead 15 on the outer side, the inner edges of the stiles and cross rails may be placed against one another' as shown in Fig. 3 and the panel plate 10 fitted against the curved portion 18, the three plates being spot welded to one another as shown.

rl`his simple arrangement of the different parts provides a paneled door with a hollow sheet metal frame of one piece so that no edge of the sheet metal is exposed to view. rllhe forms shown in Figs. 2 and l are preferred since by the insertion of the panel plate 10 between the folded edges into the hollow Stiles or cross rails the need of accurate cutting and fitting of said panel plate 10 is overcome and the cost of the door reduced. f

1n the modification shown in Fig. 5, the panel plate 16 is extended to one side at 17 and given the angular outer bend 18 at the outer edge of the door and a bead 19, between which bend 18 and bead 19 a second plate 20 is inserted as shown in dotted outline, the plate having an angular Harige 21 which fits closely between the bead 19 and thebend 18; the outer edge of the plate 20 being turned in a bead 15 and spot welded at the contacting point 22 which corresponds to the contacting point 14 in the other designs. This attains a pleasing design with the two beads 15 and 19 on the straight side of the door and a smooth and finished exterior With a hollow or boxed frame appearance and without exposed edges of the sheet metal.

I claim as new f- 1. In a door, sheet metal stiles and cross rails, said stiles and rails each having integral opposite spaced flat portions the free extremities of each of which fiat portions are formed with integral bends, a metal panel received in the spaces between said fiat portions and the bends of the latterhaving their free edge extremities engaged with the opposite side faces of the panel, and means to simultaneously' secure both of the flat portions and panel together at points between the bends and the inner sides of the flat portions so as to cause the free edge extremities of the flatl portions to closely engage opposite side faces of the panel, said flat portions being of such Width so as to constitute the sole means of support for the panels.

2. In a door, sheet metal stiles and cross rails, said Stiles and rails each having integral flat portions one of which latter has an integral bead at its free extremity, a sheet metal panel engaged with one of the flat portions so that the bead will abut one of the side faces of the panel, and means to simultaneously secure both of the fiat portions and panel together at points between the beads and the inner sides of the fiat portions, so as to cause the bead to be closely engaged With said side face of the panel, said flat portions being of such width so as to constitute the sole means of support for the panels..4

In testimony whereof I have affixed my signature in the presence of two witnesses.
